HDD Doctor is a rogue system tool that ransoms your computer while displaying fake alerts stating that there is something wrong with your hard drive. When this infection is installed it will configure itself to start automatically when you start Windows. Once started it will display a stream of alerts stating that your computer has a corruption or hard drive problem and requesting that you let it scan your computer. When the computer is scanned it will state that there are a variety of system problems and that the only way for it to fix them is for you to purchase the program. This is obviously a scam and you should not purchase this program for any reason.
As already said, when this program is running you will see numerous alerts appear when you try to run a program or as time goes by. The text of these alerts are:
HDD doctor detected an error on your hard drive when trying to access a file
C:\Program Files\Internet Explorer\iexplore.exe

It is strongly recommended to check the disk for errors.

All of these alerts are fake and should be ignored as they are only trying to scare you into purchasing the program.
As you can see, HDD Doctor was created to take control over your computer until you get frustrated enough to purchase it. It goes without saying that you should definitely not purchase it, and if you already have, please contact your credit card company and dispute the charges stating it is an computer virus. To remove this malware and other associated malware, please use the removal guide below.
Self Help Guide
If you are uncomfortable making changes to your computer or following these steps, do not worry! Instead you can get free one-on-one help by asking in the forums.
- Print out these instructions as we may need to close every window that is
open later in the fix.
- It is possible that the infection you are trying to remove will not allow
you to download files on the infected computer. If this is the case, then
you will need to download the files requested in this guide on another computer
and then transfer them to the infected computer. You can transfer the files
via a CD/DVD, external drive, or USB flash drive.
- As this program blocks you from running most executables, we need to download
a special one-shot fix that will allow us to continue with the removal of
this infection. Please download the
file and save it on your Desktop from the following link:
userinit.exe One-shot Download Link
- Once downloaded, double-click on the
icon that is now on your desktop. You should see a program briefly
run and when it is finished a message will appear stating that the one-shot
has finished. You can then proceed with the rest of the steps.
- Next we want to end any other malware processes that may interfere with
the cleanup. To do this, please download RKill to your desktop from the following
RKill Download Link - (Download page will open in a new tab or browser window.)
When at the download page, click on the Download Now button labeled iExplore.exe download link. When you are prompted where to save it, please save it on your desktop.
- Once it is downloaded, double-click on the iExplore.exe
icon in order to automatically attempt to stop any processes associated with
and other Rogue programs. Please be patient while the program looks for various
malware programs and ends them. When it has finished, the black window will
automatically close and you can continue with the next step. If you get a
message that RKill is an infection, do not be concerned. This message is just
a fake warning given by
when it terminates programs that may potentially remove it. If you run into
these infections warnings that close RKill, a trick is to leave the warning
on the screen and then run RKill again. By not closing the warning, this typically
will allow you to bypass the malware trying to protect itself so that rkill
. So, please try running RKill until the malware is no longer running. You
will then be able to proceed with the rest of the guide. If you continue
having problems running RKill, you can download the other renamed versions
of RKill from the rkill
download page. All of the files are renamed copies of RKill, which you
can try instead. Please note that the download page will open in a new browser
window or tab.
Do not reboot your computer after running RKill as the malware programs will start again.
- At this point you should download Malwarebytes Anti-Malware, or MBAM, to scan your computer for any any infections or adware that may be present. Please download Malwarebytes from the following
location and save it to your desktop:
Malwarebytes Anti-Malware Download Link (Download page will open in a new window)
- Once downloaded, close all programs and Windows on your computer, including
- Double-click on the icon on your desktop named mb3-setup-1878.1878-188.8.131.529.exe.
This will start the installation of MBAM onto your computer.
- When the installation begins, keep following the prompts in order to continue
with the installation process. Do not make any changes to default settings
and when the program has finished installing, make sure you leave Launch
Malwarebytes Anti-Malware checked. Then click on the Finish button. If MalwareBytes prompts you to reboot, please do not do so.
- MBAM will now start and you will be at the main screen as shown below.
Please click on the Scan Now button to start the scan. If there is an update available for Malwarebytes it will automatically download and install it before performing the scan.
- MBAM will now start scanning your computer for malware. This process can
take quite a while, so we suggest you do something else and periodically
check on the status of the scan to see when it is finished.
- When MBAM is finished scanning it will display a screen that displays any malware that it has detected. Please note that the infections found may be different
than what is shown in the image below due to the guide being updated for newer versions of MBAM.
You should now click on the Remove Selected button to remove all the seleted malware. MBAM will now delete all of the files and registry keys and add them to the programs quarantine. When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so. Once your computer has rebooted, and you are logged in, please continue with the rest of the steps.
- You can now exit the MBAM program.
- You can now delete the
file that is on your desktop. Please note that there is a legitimate
C:\Windows\System32\userinit.exe file that should not be deleted.
- As many rogues and other malware are installed through vulnerabilities found
in out-dated and insecure programs, it is strongly suggested that you use
Secunia PSI to scan for vulnerable programs on your computer. A tutorial on
how to use Secunia PSI to scan for vulnerable programs can be found here:
How to detect vulnerable and out-dated programs using Secunia Personal Software Inspector
Your computer should now be free of the HDDDoctor program. If your current anti-virus solution let this infection through, you may want to consider purchasing the PRO version of Malwarebytes Anti-Malware to protect against these types of threats in the future.
